Today, I improved some details of my blog, including modifying the "current position" on the topic page and article page ". In the past, there were very few columns, and they were done in an endless way (the name of the homepage> topic). now there are more columns, and more secondary columns and third-level columns are coming. this method is obviously not suitable, so I improved it. It is not difficult to use a recursive function.

The code is as follows:

Home page-> PHP learning-> ecshop secondary development-> Add ecshop to Baidu Map and support perimeter marking

The code is as follows:

// Current location-the first parameter catid is the id of the current topic, the second parameter is the title of the article, and the second parameter is blank when calling the current position of the topic.
$ This-> assign ("now_here", $ this-> now_here ($ catid, $ res ['title']);

// To explain, the catid in the topic table category is the topic id, catname is the topic name, asmenu is the parent id of the topic, and asmenu is 0 when it is a top-level topic.

Protected function now_here ($ catid, $ ext = ''){
$ Cat = M ("Category ");
$ Here = 'homepage ';
$ Uplevels = $ cat-> field ("catid, catname, asmenu")-> where ("catid = $ catid")-> find ();
If ($ uplevels ['asmenu ']! = 0)
$ Here. = $ this-> get_up_levels ($ uplevels ['asmenu ']);
$ Here. = '->'. $ uplevels ['catname']. "";
If ($ ext! = '') $ Here. = '->'. $ ext;
Return $ here;
}
Protected function get_up_levels ($ id ){
$ Cat = M ("Category ");
$ Here = '';
$ Uplevels = $ cat-> field ("catid, catname, asmenu")-> where ("catid = $ id")-> find ();
$ Here. = '->'. $ uplevels ['catname']. "";
If ($ uplevels ['asmenu ']! = 0 ){
$ Here = $ this-> get_up_levels ($ uplevels ['asmenu ']). $ here;
}
Return $ here;
}
